Just looked through my records , and two of mine did come from CalOrchids. My favorite one most likely came from SBOE, got it free from estate in La Mirada, so might as well be form CalOrchids. Too late tonight, but if I remember, I'll post pictures tomorrow.

I had for years the small Sobralia callosa. I think I got it from Andy, if I am not mistaken. It bloomed a few times for me. The only thing, I remember you had to take a picture right away, by afternoon the bloom was fading already. But the plant was easily manageable!
Other than that, we have seen many Sobralias at road sides in Ecuador, they were just gorgeous. Temps were intermediate.

Sobralia mirablis 'Pinky' first flower lasted 5 days in cooler weather, second flower lasted 1 day in triple digit temps. These are the second blooms on each growth 2 days for the one in back, third day for the one in forground at present low 80s

About 4' tall
